To all whom it may concern: I

Be it known that I,-WIL AM J. WRAY, a

citizen of-the United States, residing at.

Philadelphia,'i-n the county of Philadelphia, State of Pennsylvania, have invented a new and useful Timing Mechanism, of which the following is a specification.

My invention relates to improvements in.

timing mechanism. The object is to provide means for indicating different periods of time, one comprised within another.

I The invention comprises means for automatically indicating said included and including periods, means for automatically indicating the period of.- playing time still to elapse, means'for automatically indicating an additional period of playing time in the event of an even score, including audible signals at the. commencement and ending of said periods, and means for indicating the character of the periods pending.

Referring to the drawings, which illustrate merely by way of example, a suitable embodiment of my invention."

is a section 'on line 1010 of I have shown the invention as comprising an attachment applied to standard clock works. Itwill be understood, however, that the invention may be embodied in theclock as originally manufactured.

Referring particularly to Figs. 1 and 3,

lever 21 is fulcrumed at 42', connected at one end with actuating rod 22, and pivotally connected at the other end with the verti- I cally movable member 23, secured by guide screws 15- and 16 projecting through slots 1 '25 and 26, Member 23 is provided with, lug

riphery of member 22, see Fig. '5. Member 32 is secured to toothed wheel 33, originally forming part of the striking mechanism of the clock, and rotates withwheel 33 in the counterclockwise direction. provided wlth recess 34 in line with groove 31. The engagement of lever 29 in recess 34" arrests the movement of wheel 33.

On member 23 is" mounted the spring member 36, Spring 38, supported at 39 and 40, presses at its free end upon projec- Member 32 is This tion 37, normally to maintain member 23 in I the depressed position, .as in Fig. 1. In this position of the parts, spring 36 is out of engagement with escapement lever 41, thus permitting the normal operation of the same. Upon downward movement of rod 22, member 23 is raised against the tension of spring 38, and spring 36 engages lever 41 to lock It WIth the escapement wheel 44, see Fig. 3. At the same time, lever 29 is raised from the position resting in recess 34 to permitthe movement of wheel 33.

This position of the parts is maintained until, the rotation of wheel 33 brings recess 34 again beneath the detent finger of lever 29; whereupon member 23 resumes the depressed position and spring is withdrawnfromilever 41.

Means for arresting the movement of the timing mechanism while wheel 33 is stationary, and for startin the timing mechanism again, will now be escribed.

* Referring to Figs. 3 and 5,'upon stud 46,-

secured to the frame of the clock, is mounted the rotatlng element47, which is maintalned 1n position. of adjustment by friction of the fixed leather washer 49, the req ir d P sure of which is secured by the metal washer 50 and screw 48. Pin 51 projects through the washers into stud 46 to prevent rotation of the washers. Element 47 is provided with 5 four projecting points 52, 53 with inter- "Spring 62 supported by screws 63 and 64 engages stud 61 normally to maintain member 56 in the elevated position, as in Fig. 1.

Manually operated rod 65 is provided'for depressing member 56 against said spring tension. Member 56 carries the pawl 66, which co-operates with ratchet 55. Looking dog 68 is mounted at 69 and normally held in engagement With the ratchet by spring 70. 4 When member 56 is depressed, pawl 66 moves ratchet 55 and consequently element '47, so that a projecting portion 52 will engage lever 41, to lock it with escapement wheel 44, as in Fig. 12. When rod 65 is released, member 56 is returned'by spring 62 to its normal elevated position; pawl 66 engaging another tooth in ratchet 55.-'

With element 47 in the position shown in Fig. 12, a depression of member 56 will cause a movement of element 47 to the position shown in Fig. 1, by which movement projection 52 is withdrawn from lever 41 perinitting it to swing free of escapement wheel 44, after which the adjacent projecting portion 54 first engages the lever 41, to force it: back to the wheel, and then passes out of the path'of said lever, that is, to the position 40 shown :in Fig. 1. This operation startsthe timing mechanism.

As is well known, the game of basket ball comprises two twenty minute playing periods, a five minute rest period afterwards,

in case of a tie score, and an additional 1 five minutes play, to play off the tie. Two minute time-out periods are also allowed ;in the event of'i'njury to a player. The time-out periods are not deducted from a the actual playing time of the twenty minute periods. (No time-out isallowed during the extra five minutes play in the. event of ,a tie score.)

Means will now be described .for indicating these various periods and the beginning and termination of the same.

- low shaft 78 is secured by pin 74 to the minute hand arbor 72 of the clock, as shown in Figs. 2 and 8. The metal disk 73 is rigidly and electrically connected to shaft 78, and is provided with the two electric contact points 75 and 76, lying in a radius of disk 73 andalso in line with the minute hand of the 6 clock. Disk 73 is also provided with'the invided with binding sulating plate 77. Upon shaft 78 is loosely mounted the plate 79 of non-conducting material recessed at 87 to accommodate the escapement wheel shaft 88. The conducting element 80, having the annular portion 81 surrounding shaft 7 8, is secured to plate 79,

and is provided with binding post'82, and

contact points 83 projecting through plate- 7 9. Conducting element 84 is also secured to plate 79 and partially surrounds the annular portion 81 of element 80, and is propoints 86 projecting t rough plate 79.

A thin metal element 89, Fig. 10, is secured to plate 79 by screws 90, and is provided with aperture 91 for the pin 92. A sheet 93 of mica or similarinsulating substance, is secured back of elements 80, 84 and '89 to insulate same from the clock works.

with the transverse slot 102 through which projects the set screw 103. At the other end is provided pin 92 which projects into aperture 91 of element 89. By the movement of element 100 permitted by slot 102, plate 79 may be adjusted about its axis to advance or retard the engagement between contact points and 83 and 76 and 86.

Referring now to Fig. 7, 83 and 86 represent the contact. points indicated by similar numerals in Fig. 10. Points 83 are twenty minute contact points, and points 86 are five minute contact points. That is, in the normal or uninterrupted operation of the clock,

contact point 75 will engage a point 83 every twenty minutes; while contact point 76 will engage a contact point 86 every five minutes.

Wire 104 leads from one side of battery 105, through switch 106, to binding post 107 on the frame of clock works.

-When point 75, to which point the current is free to pass through the works from post 107, contacts with a point 83, what may be -termed'a twenty minute circuit is completed through wire 108, plate 109, wire 110 to what V may be termed game bell 111, and wire 112 Referrlng to Flg's. 2 and 8 to 11, the holto the battery.

.When point 76 contacts with a point 86, what may be termed a fi've minute circuit is completed through wire 113, switch 114, wire post and contact- 115, plate 109', wire 110,- bell 111, and wire 112 to the battery.

To the face of wheel.33, is secured a sheet of mica 116, through which project contact points 117,118 and 119 from wheel 33 (Fig;

3). To the insulating block 120, secured to the stationary framework are the contact plates 122 and 127 provided. with the binding posts 124 and 129-respectively. Plate 122 is.

' ringing of the time-out bell 133. The further rotation of wheel 33 brings point 119 rings upon the contact of point 119 with sprin 130, and fifteen seconds later bell 133 rings, upon the engagement of point 118 with spring 126, to indicate the end of 'the time-out period. At this point, detentlever 29 enters slot 34 to stop wheel 33.

This permits the descent of member 23 and the release spring 36 from lever 41 ofthe timing mechanism. The timing mechanism now resumes the registration of the actual playing time, from the point interrupted by the time out period.

While lever .41 is, held locked with the escapement wheel 73 the pendulum is held out of the perpendicular. The ,quick release of lever 41 permits the swing of the pendulum to and past the perpendicular, and this, with the impulse given by the escapeinto contact with spring 130, completing the meat wheel, enables the pendulum to pick circuit through. binding post 129 and wire 134, buzzer 135, and wire 112 to the battery, to cause the ringing of said buzzer.

The continued rotation of wheel 33 brings point 118 intocointact with spring 126, the time-out circuit is again closed, and the time-out bell 133 rings again'to indicate the end of the time-out period. This period, in the mechanism described, is of a duration of two minutes, and the period I from the first ringing of the bell 133 to the sounding of the buzzer, or Warning signal, is one minute and forty-five seconds.

The speed 'of rotation of wheel 33 and, consequently, the length of the periods between theringin of the bells and the buzzer, is control ed by fan 131 which is connected by a train of gearswith wheel 33, in the usual way.

The operation of the clock in the course ofa game of-basket ball is as follows:

Assuming the game to be started with the.

. minute hand of the clock in line with one of the twenty minute contact points 83, and, consequently, contact point 75 in engagement with. a point 83, switch 114 is open, and switch 106-closed. Rod 65 is actuated to start the timing mechanism as above described.

- bell 111, when, the next contact point 83 is engaged by point 75.

If, however, a player should be injured,

'- the game; is stopped for a period of two minutes. By drawing down rod 22, member 23 is elevated, detent 29 is withdrawn from 'slot 34 and the rotation of the'wheel 33'is-started. Spring 36 looks lever 41 with escapementi wheel 44, and stops the operas.

tion of the timing mechanismfi 'The en gagement of contact point 117:.with spring 126 causes bell 133 to ring. In one minute and forty-five seconds warning 'buz"zer 135 playing period, another team mayimme diately take the floor, the first'team resting during the playing of the period. In this event the operation of the clock continues as above described. If there is only one team, the timing mechanism may be stopped by drawing down rod 65.

If the score is even at the end of the two twenty minute periodsand the tie is to-be played oil, the device is started from the position of the parts shown in Fig. 12. Switches 106 and 114 are closed; Upon the engagement of point 76 with a point 86, bell 111 rings to call the players to the floor. Upon the engagement of point 76 with the next point 86, bell 111 rings, again to indicate the termination of, the five minute period for playing off the tie.

It'will thus be see-n that the periods of time are measured accurately and the signals sounded automatically and with impartiality. The players are also able to determine by a glance at the clock, the amount of the playing period remaining unplayed.

. It will be understood that the clock dial is sufliciently large, and that the clock'is secured to the wall or other support, at a suflicient elevation, to be distinctly seen from anyart. of the playing floor.

.As the c ock, thus positioned, is usually out of reach of the operator, the rods 22 and 65 are-provided attheir lower ends with rings, as shown in' Fig. v1. To these rings are secured cords or chains (not tance and thus bring the control of said rods 22 and 65 within the freach of the. operator, although he may be a substantial distance from the timing :mechanism.

Lever 137 is fulcrumed at 138 and is'pro-vided near its free end with the bent-over portion 139, upon which rests thesign 140 hinged at 141. The sign will thus be raised by the actuatingrod 22 when it is desired to measure the time-out period. It willbe lowered automatically at the end of said period, upon 'It will be understood that the bells and buzzer are shown merely as examples of signaling device. It is obvious that other electrically controlled devices, whether visible or audible, may be inserted in the several circuits, either as substitutes for, or
